24 Claims.

'This invention relates to closures for metallic containers and thelike.

One object of the invention resides in the provision of a closure devicefor metallic or other containers or the like wherein a bushingcooperates with the closure and wherein the closure device may bereadily applied to the container or other support.

Another object of the invention is to provide a sealing means formetallic containers and the like including a closure and a bushingcooperating to efiect ready application of the closure to the bushing,preventing removal of the closure without disrupting the seal, andthereby giving notice to the user that the container has been previouslyopened.

Another object of the invention is to provide a seal for bushingstructures in combination with a closure whereby the seal, upon removalof the g closure, will be ruptured and dislodged from the bushing and,will render the container leakable and unfit for reuse.

Another object of the invention is a seal for closures in combinationwith a bushing structure for metallic containers and the like wherebyupon removal of the closure the sealwill be ruptured thereby givingnotice to a user that the,closure hasbeen previously removed.

Another object of the invention is to provide a particular seat. andopening in the container or like support and having combined therewiththe bushing structure seated in the seat and extending through theopening and provided 5 with means to secure the'bushing inthe opening toprevent turning of the bushing with respect to the container or likesupport.

A still further object of the invention is to provide the sealing meansdirectly in the support to prevent removal of theclosure from thecontainer or like support so that upon removal of the closure, thecontainer will be disfigured and torn to give notice to' a user that thecontainer has been previously opened.

It is still further designed to provide a seal closure in combinationwith a container or like support which is of inexpensive constructionand capable of ready insertion and application to the container yetproviding a highly efilcient and durable structure, and-one whichpermits the removal of the entire contents of the container.

With these and other objects in view, the invention consists in theconstruction and novel arrangement of the parts hereinafter described,illustrated in the accompanying drawings and to provide 1 pointedout inthe claims hereto appended, it being understood that various changes inthe form, proportion and minor details of construction, within the scopeof the claims, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention. e

The invention will be more readily understood by referring-to theannexed drawings, wherein:

Fig. 18 is a fragmentary enlarged transverse 110 sectional view of aportion of the container, bushing and cap showing the application of thedifferent parts to the container or like support.

Referring now more particularly to the accompanying drawings, Aindicates a standard container or drum, preferably metal, showing theapplication of the invention. The closure and bushing structures areindicated, generally, at B, and one of the closures is shown in the topof the container and the other in the side thereof, both closures beingthe same but of different sizes. It will be understood that the closureand bushing structure might be applied to any part of a container orlike support. Where two or more closure and bushing structures areemployed, they may be of the same or different sizes.

In one form of the invention, as disclosed in Figs. 1, 2, '7, 9, 10 and11, the container or like support A is provided with a raised polygonalseat 1, having cut out or stamped therefrom a polygonal opening 2,thereby forming a recess or seat 3.

An annular bushing C consisting of a cylindrical portion 4, an externalpolygonal shoulder portion 5, and a polygonal outwardly directed flange6 is adapted for insertion within the polygonal opening 2 in thecontainer or like support. The polygonal flange 6 is of such dimensionsas to properly conform to the dimensions of the polygonal seat 3 so thatwhen the bushing is inserted through the opening the perimeter of theflange 6 will engage in and seat in the polygonal seat 3. The polygonalshoulder 5 of the bushing surrounds the bushing and is disposed on theflange 6, being of smaller diameter than the latter and extends throughthe opening and is of such dimensions and shape as to conform to thepolygonal opening 2 and serve as a guide to lead the flange 6 to theseat 3. A gasket 7 surrounds the polygonal shoulder 5 and engages theunder side of the seat 3. The polygonal formation of the flange 6 andshoulder 5 prevents turning of the bushing with respect to the containerwhen inserted therein. The polygonal shoulder 5 projects outwardlythrough the opening 2 and a circular seal'8 surrounds the same. Thisseal is preferably in the form of a ring and preferably of brittle,springy metal, but may be made of any suitable material, and has acentral opening 9. This ring seal 8 is provided on its upper face with aplurality of tongues 10 which may be struck up therefrom, and is scoredat various points, as at- 11, to weaken the ring. The circular seal 8 isalso provided with curved portions 12 and notches 13. The notches 13 areadapted to engage the corners 5' of the polygonal shoulder 5 to preventturning of the seal thereon and the curved portions 12 are between thenotches and are intermediate the corners 5' of the polygonal shoulder 5as will be clearly seen in Fig. 9.

The ring seal 8 may be scored at 11 as shown in Fig. '7 both on the topand bottom of the ring. In some instances, however, it may be desirableto only have the ring scored on its top portion or its bottom portion.

After the flange 6 has been placed on the seat 3 and the shoulder 5 andthe cylindrical portion 4 thereof are inserted through the opening 2 inthe container, an exteriorly threaded ring 14, having its lower portion15 of polygon formation and its upper portion 16 recessedcircumferentially interiorly thereof, is placed over the cylindricalportion 4 of the bushing and the polygon portion 15 of the ring extendsover the shoulder 5, as at 1'7, and contacts with the circular seal 8which has been previously placed over the polygonal shoulder 5exteriorly of the opening in the container and resting on the seat 1, asclearly shown in Figs. 10 and 11.

To secure or fasten the ring 14 on the bushing, the upper end 18 of thecylindrical portion 4 of the bushing is upset or swaged into thecircumferential recess 16 in the upper end of the ring 14 as shown at 19in Figs. 10 and 11. The upsetting or swaging of the upper end 18 of thebushing may be accomplished by hammering by hand, or by an air machine,or a drop-hammer and a leak-proof joint between the bushing andcontainer thereby formed. The ring 14 has an annular flange 20intermediate the recess 16 and the polygon formation 15, which engagesthe cylindrical portion 4 of the bushing, as best shown at 21 in Figs.10 and 11.

After the bushing has been inserted and secured within the recess andopening as above described, and after the container has been filled withany suitable contents and it is desired to seal the container, aninteriorly screw threaded cap 22 may be applied to the screw threadedring 14. The screw cap 22 is provided on its lower portion 23 with aplurality of inclined recesses 24 corresponding to the number of tongues10 on the seal 8, and

may also have an exteriorly screw threaded projection 25 centrallyinteriorly thereof which is adapted to receive a faucet or the like.

It will be seen that when the cap 22 which is provided with a portion 26for engagement of a wrench or other suitable tool is screwed down overthe threads of the ring 14 in a clockwise direction, the recesses 24will ride over the spring tongues 10 of the seal 8. However, when it isdesired to remove the cap 22 it must be done by turning the same in ananti-clockwise direction, and the spring tongues 10 of the seal 8 willproject into the inclined recesses 24 of the cap 22 and by turning thecap 22 to remove the same, the tongues will be torn from the seal 8 andthe seal will be broken at its scored portions 11 and the entire sealwill be disrupted and dislodged from between the exteriorly screwthreaded ring 14 and the top of the seat 1 upon which the seal rests.

By referring to Fig. 10, it will be seen that the curved out portions 12of the seal 8, which are 8, however, are in engagement with the corners5 of the polygonal shoulder 5 and extend to the perimeter of the polygonformation 15 of the lower portion of the ring 14 as will be clearly seenby reference to Fig. 11. In this manner, the seal 8 which rests on theupper exterior portion of the seat 1 is firmly gripped at the portionswhich are notched and engage the corners of the polygonal shoulder, thecurved cut out portions 12 are only engaged by the outer lower edge ofthe threaded ring 14, which permits of removal, dislodgment andrupturing of the seal ring 8 from between the threaded ring 14 and itsseat 1 when the cap 22 is removed. In other words, when the cap 22 isremoved, the spring tongues 10 of the seal 8 will engage in the inclinedrecesses 24 of the cap 22 and the seal 8 will be entirely dislodged andruptured and freed from between its connection with the bushing and seat1 and the bushing will then drop down and be loose within the likesupport is formed with the polygonal seat 1 and polygonal opening 2 andthe bushing C and the threaded ring 14 and the cap 22\ are all formedand assembled as shown and described above. In this modification,however, it is desirable only to rupture the seal 8 but not to dislodgeor remove the same from between the threaded ring 14 and the seat 1.With this in mind, the seal 8 in this modification is 'formed with thepolygonalopening 9 and has on its upper face the spring tongues 10. Thisseal ring 8 is applied to theshoulder of the bushing in the same manneras previously described but the portions in between the corners of thepolygonal opening 9 are not cut out, and they engage the polygonalshoulder 5 of the bushing, as at 28 in Fig. 5. The threaded ring 14engages a substantial part of. the seal 8 'acent the polygonal openingtherein as shown in ig. 3 and when the upper-portion 18 of the bushingis swaged or upset, a firm grip between the ring 14 and the seat 1 isobtained to tightly grip the seal 8 therebetween and form a leak-proofjoint.

After the closure cap 22 has been inserted on the screw threaded ring asshown in Fig. 3 and it is desired to remove the same, the spring tongueswill project into the inclined recesses 24 of the cap and the tongueswill be torn from the seal'8, but the seal will not be dislodged frombetween the threaded ring 14 and the seat 1. In other words, the removalof the cap 22 will merely rupture or tear the tongues from the seal, theseal remaining in between the threaded ring 14 and the seat 1, therebygiving notice that the cap has been removed but the container uponreplacement of the cap will be capable of reuse.

In another modification of the invention, as disclosed in Figs12, thepolygonal flange 6 having the washer 7 thereon engages in the seat orrecess 3 and the polygonal shoulder portion 5 extends through theopening 2 and outwardly of, the same. The cylindrical portion 4 of thebushing is the same as heretofore described and has the exteriorly screwthreaded ring 14 surrounding the same. In this modification, the screwthreaded ring 14 engages and rests on the seat 1, there being no sealinterposed between these two elements.

When the upper end 18 of the bushing has been upset or swaged into thecircumferential recess 16, as previously described, a tight leak-proofjoint is. formed between the bushing, ring and seat 1. The interiorlyscrew threadedcap 22 may then be turned onto the exteriorly screwthreaded ring 14 and the opening in the bushing thereby closed. In thismanner, the polygonal flange 6 resting on the polygonal seat 3 and thepolygonal shoulder 5 extending through the polygonal opening 2, turningof the bushing with respect to the container or other support isprevented and when the upper end 18 of the bushing is'swaged or upset aleak-proof joint is formed between the ring and bushing and the seat 1.The screw threaded cap in this modification is removable and replaceableat will without rendering the container unfit for reuse.

In a modification of the invention, as disclosed in Figs. 13 and 14,tongues 27 are struck up from the polygonal seat 1 of the containermetal. These tongues are'of a springy, brittle nature and the polygonalseat 1 is of somewhat wider dimensions than the other modifications ofthe invention. The flange 6' is also of greater dimension than theflange in the other modifications of the invention. The annular bushinwith the cylindrical portion 4 and the polygonal shoulder 5' isreceivable in the opening 2 of the seat in the same manner as heretoforedescribed. The exteriorly screw threaded ring 14 surrounds thecylindrical part of the bushing 4 and is provided in the same manner asshown in Fig. 7 with a circumferential recess 16 at its upper portionand a polygonal formation. at its lower portion. The upper end 18 of thebushing is swaged or turned over into the circumferential recess 16 andthereby forms a leak-proof joint between the ring 14 and the seat 1 Arelatively wide gasket 28 rests on the polygonal flange 6*- and sealsthe openings 29 formed by the struck up tongues 27. An interiorly screwthreadedcap 30 having inclined recesses 31 in its lower portion isadaptable for engagement with the ring 14 to close'the opening in thebushing. It will be seen in Fig. 14 that when the cap has been screweddown to its lowermost position, the tongues 27 project into the inclinedrecesses 31. Upon the removal of the cap 30, the tongues 27 in the seat1 will be torn and disrupted and give notice to a. subsequent user thatthe container has beenpreviously opened. In this modification of theinvention, instead of using the separate seal 8 as disclosed in theother modification of the invention, the tongues-27 are formed integralwith the container or like support. The tongues 27 are scored as at 27'.These tongues may be scored either on their top or bottom or both on thetop and bottom as in the invention disclosed in Fig. 7. Upon removingthe cap 30, the tongues 27 will be torn at their scored portions 27' andthereby give notice to a user that the container has been previouslyopened:

It is to be noted-that the flanges 6 and 6 when in the recess or seatare flush with the interior of the container or the like and provide forcomplete drainage of the contents thereof.

In the modification of the invention as dis- In the modification of theinvention as illus+ j trated in Figs. 15 to 18, inclusive, it will beseen that the present invention may be positioned from the outside ofthe container and extend and extend exteriorly thereof as heretofore'described. It will also be noted that in this lastmentionedmodification, a different type of closure proper is employed or may beused with this latest modification. In order that the invention may beapplied from the outside rather than from the inside of the containenitwill be stated that thebushingis positioned in the head or bottom orbody of the container prior to the application of the head and bottom tothe body. The fact is that in all forms of the invention, the deviceherein claimed is applied to difierent parts of the container prior toassembling the container. It will also be understood that the device maybe applied to a side wall of the body of the container rather than tothe bottom or head. It will also be understood that this modified formof the invention may be applied to the head or to the side of thecontainer as proposed in other forms of the invention and as illustratedparticularly in Fig. 1. If the device is placed in the head of thebarrel, it does not project beyond the edges of the chime of the barreland if placed in the side wall of the container, the closure does notproject beyond the outer edges of the common rolling beads or hoops,

such as shown in Fig. 1 and thereby when the container is of cylindricalform and rolled, there is no danger of the closure contacting withobstacles and resulting in a bumping of the container as it is rolledalong a skid or other supporting surface.

So, now, referring specifically to Figs. 15 to 18, inclusive, there isillustrated'a sheet metal or other container A provided with a head 32which is secured to the side wall 33 of the container in the customarymanner as at 34. A repressed polygonal seat 35 provided with a polygonalopening 36 is formed in the head 32 of the container. An annular bushing37 consisting of a polygonal flange 38, a polygonal shoulder portion 39and a cylindrical portion 40 is adapted for insertion within the opening36. The polygonal flange 38 of .the annular bushing rests in thepolygonal seat 35. A washer 41 is interpositioned between the under sideof the flange 38 and the top of the seat 35. The polygonal shoulderportion 39 of the bushing extends through the polygonal opening 36 asdoes also the cylindrical portion 40. A ring 42 provided withacircumferential recess 43 in its lower portion and an interior polygonalrecess 44 at its upper portion surrounds the bushing 37 interiorly ofthe container. The in terior polygonal recessed portion 44 of the ring42 engages the polygonal shoulder 39 and the outer cylindrical portion45 is swaged or overturned into the circumferential recess 43 in thering thereby forming a leak proof joint between the ring ,and bushingand the bottom or the interior part. of the polygonal seat 35. Theformation of the polygonal flange 38 resting in the polygonal seat 35and the polygonal shoulder 39 engaging in the polygonal opening 36 willprevent turning of the bushing with respect to the container, and asbefore stated the overturning" of the end 45 of the bushing will form aleak proof joint between the ring, bushing and the container. The ring42 will also be prevented from turning by its engagement with thepolygonal shoulder 39 of the bushing.

A circular seal'ring 46.is adapted to rest on and be secured to the topor the upper exterior portion of the polygonal flange 38. This seal ring46 is provided with a plurality of struck up tongues 47 which are scoredas at 48 either on their top or bottom or both the top and bottom. Thering has a central opening 49. The ring is provided with a plurality ofbendable ears 50. After the ring has been placed on the top of theflange 38 the ears 50 are bent around the outer edge of the polygonalflange in engagement with the under side thereof as at 51, thuspreventing turning of the circular seal with respect to the polygonalflange 38.

The annular bushing 37 is interiorly screw threaded as at 52. :,Theopening 49 in the circular seal is so dimensioned that when applied ontop of the polygonal flange 38 it will be spaced from the screw threads52 of the annular bushing. A suitable washer or gasket 53 abuts theinner edge of the circular seal 46 and extends substantially flush withthe screw threads 52 of the bushing on the top of the flanged portion38. An exteriorly screw threaded cap 54 provided with screw threads 55and having a circumferential flange 56 which is provided on its lowerportion with inclined recesses 57 corresponding in number to the tongues47 on the circular seal 56 is adapted to be threaded into the annularbushing and engage the screw threads 52 of the bushing.

It will be seen that when the cap 54 is threaded into the bushing 37 ina clockwise direction the inclined recesses 5'7 will ride over thetongues 47 of the circular seal 46 until thelower portion of thecircumferential flange 56 seats on top of the seal 46 and the gasket orwasher 53, thereby forming a leak proof sealed closure for thecontainer. When, however, it is desired to remove the cap 54, the samemust be turned in an anti-clockwise directon and by doing so the tongues4'? of the circular seal 46 will break at their scored portions 48 andgive notice to a user that the container has been previously opened. Thecircular seal 46 upon opening the container, that is, removing the 'cap54, will not be dislodged from its connection with the polygonal flange38 ,of the bushing. The tongues 47 will merely be torn from the ringseal and give notice that the container has been opened. It is to beunderstood that in assembling the bushing which carries the ring seal 46on its flanged portion in the polygonal seat 35, the bushing and theoverturned ears 50 of the circular seal will-contact with the walls ofthe polygonal seat 35 and turning of the bushing will be prevented as inthe other forms of the invention described herein.

From the above, it will be clear that we have provided a novel polygonalseat and opening in a container or like support in combination with aparticular formation of annular bushing and having the seal cooperatingwith the bushing and closure to either remove or dislodge the sealentirely from between its connection with the bushing and form aleakable joint, or else merely disfigure or rupture the seal withoutremoving the same from between its connection with the bushing andcontainer. In some instances it is desirable to have no seal at all andmerely provide our novel polygonal seat and bushing structure, and inothers the seal is formed integral with the container or like support.This unique arrangement of parts provides a highly desirable andefflcient screw seal closure and bushing structure which is adaptablefor use with steel drums, barrels, etc. or as a matter of fact, the samemight well be used anywhere wherein a closure and seal of this kind isdesirable.
